Gaps in shielding are more likely to occur where different forms of shielding meet. Typical problems
encountered are:
• There may not be sufficient overlap between walls and shielded doorframes/window frames. Similarly there
may not be sufficient overlap between shielded doors and doorframes or windows and window frames.
• The integrity of the joints between lead sheets may not be sufficient.
• Where sockets, switches, plumbing, or ducting, etc. breach the shielding, these areas may not be
adequately protected.
• Joints between ceilings and walls may not be adequately shielded.
• Panels, where the lead lining does not extend the full length of the panel, may be installed incorrectly
(Section 6.3.1).
These problems can be detected by checking boundary transmission at the appropriate places.
